Question No: 21 – (Topic 3)

You need to configure availability for the virtual machines that the company is migrating to Azure.

What should you implement?

Traffic Manager

Express Route

Update Domains

Cloud Services

Answer: B

Explanation: ExpressRoute gives you a fast and reliable connection to Azure making it suitable for scenarios like periodic data migration, replication for business continuity, disaster recovery and other high availability strategies. It can also be a cost-effective option for transferring large amounts of data such as datasets for high performance computing applications or moving large VMs between your dev/test environment in Azure and on- premises production environment.

Question No: 22 HOTSPOT – (Topic 3)

You need implement tools at the client#39;s location for monitoring and deploying Azure resources.

Which tools should you use? To answer, select the appropriate on-premises tool for each task in the answer area.

Answer:

Explanation:

C:\Users\Chaudhry\Desktop\1.jpg

System Center Virtual Machine Manager (SCVMM) enables rapid provisioning of new virtual machines by the administrator and end users using a self-service provisioning tool.

System Center Operations Manager (SCOM) is a cross-platform data center management system for operating systems and hypervisors. It uses a single interface that shows state, health and performance information of computer systems. It also provides alerts generated according to some availability, performance, configuration or security situation being identified.

The basic idea is to place a piece of software, an agent, on the computer to be monitored.

The agent watches several sources on that computer, including the Windows Event Log, for specific events or alerts generated by the applications executing on the monitored computer.

Mitigate the need to purchase additional tools for monitoring and debugging.

Use advanced monitoring features and reports of workloads in Azure by using existing Microsoft tools.

Topic 4, Lucerne Publishing Background

Overview

Lucerne Publishing creates, stores, and delivers online media for advertising companies. This media is streamed to computers by using the web, and to mobile devices around the world by using native applications. The company currently supports the iOS, Android, and Windows Phone 8.1 platform.

Lucerne Publishing uses proprietary software to manage its media workflow. This software has reached the end of its lifecycle. The company plans to move its media workflows to the cloud. Lucerne Publishing provides access to its customers, who are third-party companies, so that they can download, upload, search, and index media that is stored on Lucerne Publishing servers.

Apps and Applications

Lucerne Publishing develops the applications that customers use to deliver media. The company currently provides the following media delivery applications:

->Lucerne Media W – a web application that delivers media by using any browser

->Lucerne Media A – a mobile app that delivers media by using an iOS device

->Lucerne Media N – a mobile app that delivers media by using an Android device

->Lucerne Media D – a desktop client application that customer#39;s install on their local computer

Business Requirements

Lucerne Publishing#39;s customers and their consumers have the following requirements:

->Access to media must be time-constricted once media is delivered to a consumer.

->The time required to download media to mobile devices must be minimized.

->Customers must have 24-hour access to media downloads regardless of their location or time zone.

->Lucerne Publishing must be able to monitor the performance and usage of its

customer-facing app.

Lucerne Publishing wants to make its asset catalog searchable without requiring a database redesign.

->Customers must be able to access all data by using a web application. They must

also be able to access data by using a mobile app that is provided by Lucerne Publishing.

->Customers must be able to search for media assets by key words and media type.

->Lucerne Publishing wants to move the asset catalog database to the cloud without formatting the source data.

Other Requirements Development

Code and current development documents must be backed up at all times. All solutions

must be automatically built and deployed to Azure when code is checked in to source control.

Network Optimization

Lucerne Publishing has a .NET web application that runs on Azure. The web application analyzes storage and the distribution of its media assets. It needs to monitor the utilization of the web application. Ultimately, Lucerne Publishing hopes to cut its costs by reducing data replication without sacrificing its quality of service to its customers. The solution has the following requirements:

->Optimize the storage location and amount of duplication of media.

->Vary several parameters including the number of data nodes and the distance from node to customers.

->Minimize network bandwidth.

->Lucerne Publishing wants be notified of exceptions in the web application.

Technical Requirements Data Mining

Lucerne Publishing constantly mines its data to identify customer patterns. The company plans to replace the existing on-premises cluster with a cloud-based solution. Lucerne Publishing has the following requirements:

Virtual machines:

->The data mining solution must support the use of hundreds to thousands of processing cores.

->Minimize the number of virtual machines by using more powerful virtual machines. Each virtual machine must always have eight or more processor cores available.

->Allow the number of processor cores dedicated to an analysis to grow and shrink automatically based on the demand of the analysis.

Explanation: * Microsoft Azure Traffic Manager allows you to control the distribution of user traffic to your specified endpoints, which can include Azure cloud services, websites, and other endpoints. Traffic Manager works by applying an intelligent policy engine to Domain Name System (DNS) queries for the domain names of your Internet resources.

Your Azure cloud services or websites can be running in different datacenters across the world.

* Scenario:

Virtual machines:

->The data mining solution must support the use of hundreds to thousands of processing cores.

->Minimize the number of virtual machines by using more powerful virtual machines. Each virtual machine must always have eight or more processor cores available.

->Allow the number of processor cores dedicated to an analysis to grow and shrink automatically based on the demand of the analysis.

/ Lucerne Publishing must be able to monitor the performance and usage of its customer- facing app.

* Scenario: The customer-facing website must have access to all ad copy and media.

Question No: 29 – (Topic 4)

You need to ensure that the website scales. What should you do?

Deploy Traffic Manager and configure it to route user traffic to specified endpoints to other Azure datacenters.

Enter multiple DNS entries in each virtual network to route requests to other Azure datacenters.

Set up a new Azure datacenter to Azure datacenter VPN to enable the solution to communicate across regions.

Use a virtual network to route network traffic in a single Azure datacenter.

Answer: C

Explanation: Scenario: The customer-facing website must automatically scale and replicate to locations around the world.

Azure ExpressRoute enables you to create private connections between Azure datacenters and infrastructure that’s on your premises or in a colocation environment. ExpressRoute connections do not go over the public Internet, and offer more reliability, faster speeds, lower latencies and higher security than typical connections over the Internet. In some cases, using ExpressRoute connections to transfer data between on-premises and Azure can also yield significant cost benefits.
